A Police Detective Has Just Received a List of Evidence

A police detective has just received a list of evidence collected at the scene of a murder which occurred in the victim's bedroom, which includes:
•Several blood samples were recovered from the area where the victim bled to death
•Bullets were recovered from the wall behind the victim's body
•Fingerprints found on a window that appeared to be the point of entry Would sending the bullets to a ballistics expert be a good idea?

A) Yes, test should be high priority because the ballistics examiner will be able to tell what model gun was used.
B) Yes, but it is not urgent because the ballistics expert cannot match the bullet until a gun has been recovered and test fired.
C) No, ballistics testing is only allowed if the gun was found at the crime scene.
D) No, because any usable evidence was destroyed when the bullet was lodged in the wall.
